A highly unusual version of a slave-ship diagram as an anti- slavery broadside. There is considerably more detail to the drawing of the slaves within the hull of this ship than is usually seen on the broadside depictions of the ships Brooke or Vigilante. As the caption beneath explains: while Spain and Portugal had been signatories to the 1807 ban on taking slaves from Africa, the practice not only persisted but as many as 17000 slave passed through Rio de Janeiro in a six month period.Engraved broadside diagram with captions.
